Claims.

This invention relates to assembling machines. and more particularly tolmachines for assembling crystal units.

In the manufacture of certain types of quartz crystal units, the crystalis enclosed in a housing and it is important that the housing as well asthe crystal be freed of moisture.

An object of the invention is to provide an assembling machine which ishighly efficient and practical for use in assembling articles intounits.

With this and other objects in view, the invention comprises anassembling machine having a support to move articles to be assembled ina given path, means for use in assembling certain of the articles withconnecting members to form units thereof, and means actuated at givenintervals to deposit a sealing material on the connecting members. v

Other objects and advantages will be apparent from the followingdetailed description when considered in conjunction with theaccompanying drawings, wherein Fig. l is a, top plan view of themachine, portions thereof being broken away;

Fig. 2 is a side elevational view of the machine, portions thereof beingbroken away;

Fig. 3 is an enlarged vertical sectional view of a portion o f themachine, illustrating the depositing of the sealing material on theconnecting members or screws of the units;

Fig. 4 is an enlarged fragmentary detailed View taken along the line 4-4of Fig. 1, and

Fig. 5 isa fragmentary detailed sectional view taken substantially alongthe line 5-5` of Fig. 3.

Referring now to the drawings, attention is first directed to Fig. 1,which illustrates a support or turret I0 movable about its axis at agiven low speed, approximately one revolution every half hour, to moveunits formed of the articles, namely casings II (Fig. 4) and theircovers I 2, at spaced locations in the given circular path. Thesearticles are moved throughl an oven i4 in which a series of heatinglamps I 5 are disposed to heat thearticles and to drive' off allmoisture therefrom. This result is accomplished although the units arepartially assembled manually prior to their entering the oven by placingthe covers upon their respective caslngs and positioning retainingmembers, such as screws I6 (Figs. 3 and 5), in the apertures providedtherefor in the articles. Sealing washers I'I space the articles apartso that moisture may be driven from the inside of the casings Il.Through the aid of an air-driven screw driver t I8, the screws I6, therebeing two in number for each unit, may be simultaneously driven l untilthe covers for each unit are uniformly secured in place. The unitsremain at fixed positions upon the support I0 and continue their traveltoward and past a sealing unit I9, where, under the control of eachunit, means is actuated to cause ejection of quantities of sealingmaterial 20 (Fig. 3) to be forced or caused to drop into the aperturesover the screws I6.

Considering now the specific structure of the machine, atttention isdirected to Fig. 2, which illustrates a frame 22 supporting theremaining structure of the machine including an electric motor 23 whichdrives a speed reducing unit 24, an output shaft 25 of which has apinion 2B mounted thereon. The pinion 26 drives a bevelled gear 2l,which-is fixedly mounted upon a vertical shaft 28, the latter beingsupported by a bearing bracket 29. A pinion 30, fixed to or formedintegral with the shaft 28, drives a ring gear 3|, which is xed to theunder surface of the support I 0, to thus move the support at agivenspeed about its axis. Thesvsupport I0 has an integral hollowcylindricall portion 33 which serves as a hollow shaft rotatable about avertical stationary hollow shaft or structure 34, the latter being xedin any suitable manner to the frame 22. A table 36 is mounted upon thefixed shaft 34 and assists in supporting the upper structure of themachine.`

The oven I4 is supported by suitable brackets 38 'and 39 and is providedwith suitable insulating material as indicated at 40. The oven is alsoformed to receive the articles II and I2 for their movement into,through and out of the oven.

The screw driver unit I8 is supported as illustrated in Figs. 1 and 2,and may be of any desired structure including screw driver elements 42disposed at given positions corresponding to the spaced positions of thescrews I6 and driven .by air under pressure or other suitable powermeans. The detailed structure of the unit I 8 will not be specificallyshown or defined, as it is tobe claimed generally. The screw driver unitI8 is supported by a bent pipe or tubular member 44 supplied with airunder pressure from a supply line 43 connected to the screw driver unitthrough lines 46 and 41.' The screw driver unit includes a hose portion48 flexible so that the head 49 supporting the screw driver elements 42may be moved.

to the necessary positions during theA continuous movement of thesupport I0.

The sealing unit I 9- supported by the fixed hollow shaft 34 extendsoutwardly therefrom to a position above the articles on the support I8.The outer end of the unit I8 includes a housing 45 having a cover 48therefor hlngedly mounted at 41. A receptacle 48 is disposed in thehousing 45 and extends through an aperture 48 in a bottom wall 58 of thehousing. Two .iets or nozzles of the cross-sectional contour illustratedin Fig. 3 extend through apertures in the bottom wall of the receptacle48 and are provided with vertical apertures or passageways 52 andhorizontal passageways 58. The upper portions of the verticalpassageways 52 are enlarged to receive. valves 55, which are normallyheld closed, to close both apertures 52 and 58 by the aid of springs55.'

The springs 58 are disposedconcentric with the valve stems 51, whichextend vertically into guides 58, the latter beingintegral portions of acover 59 of the receptacle. Collars 88, mounted upon their respectivevalve stems 51 and ilxed thereto, are disposed beneath the springs 58and receive the forces therefrom to hold their respective valves 55closed.

A fiat plate 52, apertured to receive reduced upper ends 63 of thenozzles or jets 5|, is held in place by the aid of a bolt 84 and is onlyslightly larger in width than the diameter of the reduced portions 63,so that the opposing sides of the receptacle 48, which is cylindrical incross-section, may be free for the passage of sealing material 28 topass therethrough. The sealing material is not shown in Fig. 3 otherthan the deposits thereof in the apertures over the heads of the screwsor connecting members I8, but it should be assumed that the receptacle48 may be substantially filled with the sealing material, which in thepresent instance is a suitable lacquer. The cover 58 is normally heldclosed through the aid of thumb screws 88 and may be removed from thereceptacle by the opening of the cover 46 of the housing 45, so that thesealing material may be disposed within the receptacle.

The power means for opening the valves 55 includes a solenoid 88 mountedin the housing 45 and including a core 58 pivotally connected at 18 toan actuating member 1|. The member 1I is pivotally supported at 12, thelatter being carried by a vertical frame 13. The frame 13 has outwardlyprojecting integra1 portions 14 which carry variable stop screws 15 and18; the latter having helical springs 11 disposed concentric therewithfor a purpose hereinafter described. An arm 18 is integral with theactuating member 1| and is positioned between the upper stops 15 and 18,the former governing the normal position of the actuating member, whilethe latter limits the actuating movement of the member, the adjacentspring in turn serving to normally hold the arm 1n engagement with itsrespective stop screw 15. A latch 8I is pivotally connected at 82 to theactuating member 1| and is normally urged counterclockwise by a spring88. A tooth 84 of the latch 8| is positioned to engage a companion tooth85 of an actuating element 88, the latter having its adjacent endmounted upon the pivot 12. The element 88 is provided with an arm 88integral therewith and extending between the lower stop screws 15 and 18and controlled thereby as well as by the adjacent spring 11. The outerend of the element 88 is blfurcated, as at 88, to straddle a connectingrod 8| which extends through a bushing 82 in the cover 58. A lateralmember 83, carried by the inner end of the rod 8|, is apertured for thevalve stems 51 and supports the collars 68 thereof. Suitable washers 85serve to seal the bushing 82 when the rod 8| is in its uppermostposition. A threaded member 88, disposed upon a threaded portion 81 ofthe rod 8|, is engaged by the bifurcated end 88 oi the element 88 toprovide connection between the element and the rod.

Through this connection energization of the solenoid 88 will move theactuating member 1| counterclockwise to move the actuating element 86,through the connection o! the latch 8|, in the same direction, to movethe rod 8| upwardly and with it the valves 55. The amount of movementimparted to the rod may be determined through the positioning of thethreaded member 85. During this upward movement of the valves, a pin|88, carried by the latch 8|, rides upon a cam |8I to cause the latch tobe freed of the actuating element 88 at a given position and thusdisconnect'the actuating elements from the actuating member 1| and allowthe valves 55 to be closed.

The sealing material in the receptacle 48 is forced in given quantitiesthrough the iets 5| by the application of air under pressure to thesupply of the material in the receptacle. Air is supplied to thereceptacle from the supply line 48. through the pipe line 44, through aline |88 which includes a pressure reducing valve |84, and into theupper end of the receptacle 48. Thus with the constant application ofair under pressure to the sealing material, or with its application' atgiven intervals, the valves 55 need to be opened only momentarily.

The control for the actuation of the valves 55 and the energization ofthe solenoid 88 extends to the units formed by the articles I and I2 andiocated on the support I8. In other words, a switch |88, mounted in thehousing 45 and of the normally open type actuated into closed positionby a spring actuated plunger |88, is included in anelectrical circuit(not shown) to cause energize.- tion of the solenoid when closed. An armHI, positioned in engagement with the plunger |88, is normally heldagainst a stop I by the force of a spring |I2. The arm ||8 is xedlymounted upon a vertical shaft I|4, which extends downwardly through abearing II5 (Fig. 3) fixedly mounted in an aperture of the base orbottom portion 58 of the housing 45. An enlarged portion I|8 of theshaft II4 carries a resilient arm I|1, bent at its outer end, as at I|8(Fig. 5), to provide a rounded portion positioned to be engaged by theunits as they move successively on the table into the finishing positionbeneath the unit I8. I'he arm I|1 is positioned so that when actuated byone of the units to cause rotation of the shaft II4 against the force ofthe spring |I2, to cause the arm I|8 to actuate the plunger |88 to closethe switch |88 and thus cause energizetion of the solenoid 88, resultingin the opening of the valves 55, the unit, which caused this train ofaction, will be disposed with the screws or connecting members |8 indirect alignment with the jets 5|, to receive the quantities of thesealing Vmaterial 28 therefrom.

Considering now the operation of the machine. the articles il and I2 arealternately disposed upon the support I8 at a position indicatedgenerally at |28 (Fig. 1). In viewing Fig. 4, it will be noted thatspacers |2I are mounted like distances apart on the support to receivethe articles I and i2 in alternate positions therebetween. As previouslydescribed, the article I is in the form of a casing, while the articleI2 in the present embodiment is a, cover therefor including hollowterminals |22. To further describe the cover i2,

' supporting wires mounted in the hollow terminals |22 and have supplyoi' articles II and these apertures in the jets and into the aperturesof the covers or articles I2 provided for the screws or connectingmembers I6. The valves 55 are held open momentarily until the latch 8|is tripped by the cam I allowing the springs 56 to return the valves 55to their closed positions.

again i'onned therebetween through the aid ot the latch 8|.

It will, therefore, be observed that through the continuous rotation ofthe support i0 resulting from the energization o1' the motor 23 and itsdriving connection through to the ring gear 3l, the completed units maybe removed from the support after they pass the unit i3 and a new I2 maybe alternately disposed upon'the support to travel through the oven I 4to be What is claimed is:
